Summary: This study tracks the changes in deep-sea mussel cell and their endosymbiotic bacteria at the ultrastructural level during an extended starvation period. It found that the cells undergo apoptosis, the host bacteriocytes lose their endosymbionts due to starvation, and suggests that intercalary cells may serve as stem cells to replace lost bacteriocytes.

Summary: This study reveals the reversible evolutionary shifts from interstitial to epibenthic habitats in the polyclad flatworm genus Boninia. Two new species of this genus were found on a single beach in Okinawa Island, Japan, indicating independent colonization rather than descent from a common ancestor. Molecular phylogenetic analysis suggests that the interstitial species are not monophyletic among the epibenthic species.

Summary: The study found significant diversification of Dactylogyrus species in the Middle East, with different phylogenetic lineages indicating possible convergent evolution of morphological traits in different species. The under-explored parasite diversity in many regions highlights the importance of studying host-associated parasites in the context of freshwater fish biogeography.

Summary: Interbacterial competition is common in host-associated microbiota and can impact community structure and function. This study identifies a putative lipoprotein that mediates cell-cell attachment and allows targeted elimination of specific competitors. The findings have implications for understanding the impact of competition on microbiome structure.

Summary: Plant root architecture is developmentally plastic and forms dedicated cells and organs to host symbionts, such as nitrogen-fixing nodules and myconodules. These symbiotic associations provide different levels of compartmentalisation, allowing the plant to regulate symbiotic interactions. This review discusses the developmental strategy of symbiont compartmentalisation by the plant host and speculates on how spatial confinement mitigates risks associated with root symbiosis.

Summary: In the ocean, the Lucinidae family of marine bivalves is the most species-rich and widely distributed, hosting autotrophic bacterial endosymbionts. Metagenomics research revealed a cosmopolitan symbiont species associated with multiple lucinid host species, challenging our understanding of symbiont dispersal and location-specific colonization. This discovery highlights the importance of host and symbiont flexibility in the ecological and evolutionary success of the lucinid symbiosis.

Summary: Symbiotic associations between bacteria and ciliate protists are common, and several cases involving Rickettsiales bacteria have been reported. In this study, a novel ciliate protist strain from Brazil and its associated Rickettsiales endosymbiont were characterized. It was found that Candidatus Trichorickettsia has the ability to infect multiple host species, highlighting the importance of further research on flagella and their regulation in this system.

Summary: This article describes various methods for collecting and preserving bark and ambrosia beetles, including collecting tools, recording data, and step-by-step beetle extraction techniques. It also elaborates on trapping techniques, tools, attractants, and beetle preservation. The key rule for manual collecting is to separate the wood or bark from the beetle gently and systematically, instead of trying to pry the insect out. The main rule for trapping is to use attractants and traps that reflect the ecology of the targeted beetle species.

Summary: This study investigates the symbiotic relationship between the mulberry seed bug and Caballeronia symbionts using various methods. The results show that the Caballeronia symbionts are harbored in the posterior midgut crypts of the mulberry seed bug, and this symbiotic relationship is crucial for the development and survival of the bug.

Summary: This paper proposes a methodology to support the design of regional industrial symbiosis networks (ISNs), including the construction of a waste-input relationship table and the identification of potential symbiotic synergies. The methodology is tested in the Apulia region of Southern Italy, where more than 300 feasible IS synergies are identified. The method is useful for companies interested in harnessing the benefits of IS and for regional policymakers aiming to implement IS.

Summary: This study found two known representatives of Holospora-like bacteria, Candidatus Gortzia yakutica and Preeria caryophila, in new hosts Paramecium nephridiatum and Paramecium polycaryum, respectively. The bacteria were investigated using morphological and molecular methods, providing details of their electron microscopic structure. The ultrastructural description of Pr. caryophila revealed previously unknown features and the new combinations of Holospora-like bacteria with ciliate hosts were discussed from biogeographical and ecological points of view.

Summary: A phyloprofile analysis of Frankia genomes identified genes present in symbiotic strains and absent in non-infective strains. The role of the carbonic anhydrase gene (can) was analyzed, revealing its function in maintaining pH balance and NH4+ concentration. Genes related to can have undergone decay in non-symbiotic lineages.

Summary: A new genus of marine Stilbonematinae is discovered from the Pacific coast of the United States, living in sulfidic sediment and near the roots of surfgrass. Their ectosymbiotic coat is of a new type, consisting of rod-shaped bacteria densely attached to the host cuticle. This is the first report of this symbiotic nematode subfamily from the US West Coast.

Summary: We developed a new method CHEMHIST to connect anatomical structure and metabolic function in millimeter-sized symbiotic animals, addressing the limited understanding of metabolic interactions between these animals. By combining MSI and micro-CT, we successfully correlated the distribution of metabolites with the 3D histology of the animals, providing a methodological groundwork for understanding the roles of these symbiotic animals in ecosystem functioning.

Summary: Symbiotic N-2-fixing microorganisms play a crucial role in nitrogen assimilation by eukaryotes in nitrogen-limited environments. The symbiotic relationship between 'Candidatus Celerinatantimonas neptuna' and its host Posidonia oceanica allows highly productive seagrass meadows to thrive in the Mediterranean Sea. This symbiosis is similar to that of terrestrial N-2-fixing plant symbioses and may have enabled flowering plants to thrive in nitrogen-poor marine habitats.

Summary: The assembly of neuronal and other major cell programs occurred early in animal evolution. Through studying non-bilaterians like placozoans, we can reconstruct this process and understand the affinities of peptidergic cells. Our findings show that key neuronal developmental and effector gene modules evolved before cnidarian/bilaterian neurons, highlighting the importance of paracrine cell signaling.
